Abstract (en)
[origin: EP3832540A1] Disclosed is a product positioning method, the method comprising: collecting a product picture; performing integral image calculation on the product picture; and acquiring, according to the calculated integral image, coordinates of each vertex in the product picture by means of differential calculation. According to the present application, an integral image algorithm is applied to product positioning, such that when the product picture quality is not high, for example, the picture is blurry, and it is thus not convenient to position a product by using a picture edge algorithm or a template matching algorithm, the product picture and a background region can be quickly divided by using the integral image algorithm, thereby positioning the product and not being limited by poor picture quality.
